Solar powered hand washing machine

A communal hand washing facility is defined in this project as a machine to be fabricated that can be stocked within emergency response scenarios,clinics,schools churches and so on.Hand washing has been an ongoing campaign for long especially after visiting toilets, before meals and any other purpose that necessitates hand washing of which failure to do it can lead diseases. In this project,a machine using cheap plastic ...more »

SOLAR DISTILLATION

Not to be confused with solar sterilization or disinfection, solar distillation purifies even muddy, salty or otherwise undrinable water through evaporation and condensation. The power of distilation to purify saltwater makes it unique among the treatment methods featured on this page. A solar still can actually be a cheap and simple piece of shaped plastic or glass, or they can be more highly designed devices. To work, ...more »

The Sun-powered Water Well Solution

The main source of drinking water must be protected from deliberate pollution and spread of disease like guinea worm. The water is shared with animals, and is used by humans for cooking and drinking in the villages of Africa. Our solution to this program is to integrate a Sun-powered Water Well into the villages of Africa. This Water Well is eco-friendly and environmentally safe. As opposed to similar Merry-go-round ...more »

SOLAR STERILAZATION.

Solar sterilization If cost is a bigger concern than time or convenience, the cheapest way to treat water is to leave it in a plastic bottle in the sunlight. Leave clear bottles in the sun for a few hours and the UV radiation and heat kills the microbes that cause diarrhea and other waterborne illness. The Sodis (for solar disinfection) method was deployed in some parts of Haiti after the earthquake in 2010, and it is ...more »

Briefly How Solar Disinfection (SODIS) Works.

Exposure to sunlight has been shown to deactivate #diarrhea-causing organisms in polluted drinking water. 3 effects of solar radiation are believed to contribute to the inactivation of pathogenic organisms. #1. UV-A interferes directly with the metabolism and destroys cell structures of bacteria. #2. UV-A (wavelength 320-400mm) reacts with oxygen dissolved in the water and produces highly reactive forms of oxygen (oxygen ...more »

local solar disinfection

This simple technique requires only a few plastic bottles and sunlight. Firstly, collect several bottles (0.3 to 2.0 litre) made of clear plastic, remove all labels and wash them thoroughly. Fill the bottles with water of low turbidity and shake for about 20 seconds to aerate the water. Expose the bottles to the sun by placing them on a roof or rack for at least six hours (if sunny) or two days (if cloudy) . The water ...more »

Solar Powered Ultraviolet water treatment Device

SOLAR POWERED ULTRAVIOLET WATER TREATMENT DEVICE Introduction Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV energy penetrates the outer membrane, passes through the cell body then disrupts DNA stopping reproduction. UV treatment does not ...more »

solar as a tool for water purification.

My name is Adrine and i have good experience in the water business or sector and in my view (and if any one disagrees please give me a strong reason) there is no way Africa and for examplw Uganda in particular will ever meet the MDG goal 7c if we do not consider water purification using solar. We all know that electricity is still a chsllenge but we have the technology right infront of our eyes but we ignore it. well ...more »

Elevated borehole Reservoir system

After discussions with a colleague with extensive experience in ground water research and borehole pumping projects, I learned that ground water extraction by means of solar powered borehole pumps have been proven quite successful in providing a considerable quantity of fairly clean, drinkable water to farms and rural communities. It is also a fairly simple system that works independently, requires little maintenance; ...more »

Artificial leaf makes clean energy from dirty water

If one day in the not too distant future you can go to the dollar store, buy a thin, flat device the size of a playing card, dunk it in a quart of dirty bath water and use it to generate about 100 watts of electricity 24 hours a day, you can thank the Air Force. Along with other federal agencies, the Air Force Office of Scientific Research has been pouring funds into the development of an “artificial leaf,” a low cost ...more »

Cheap Solar helical rotor pumps

We can very well see that there are some areas in Africa that has rivers but lack the means to connect these rivers for the use of its water in house holds and farms. This is because they lack electrical power to aid in the activity. Solar water systems use the power of the sun to drive a submersible electric pump and are ideal for boreholes with a high yield. The pumps I am setting on is the - helical rotor pumps - ...more »
